Port of Bocca d'Arno, Marina at the mouth of the Arno in Marina di Pisa, Italy

The Port of Bocca d'Arno is a marina at the mouth of the Arno in Marina di Pisa, inaugurated on 30 June 2013. It lies on the left bank with a basin of about 50 berths and depths of 3.5 to 5 metres. The design by Modimar and 3c+t Capolei Cavalli kept the coastline unchanged and added a wide panoramic pedestrian promenade.

The marina opened on 30 June 2013, after the first stone was laid on 26 April 2010 by minister Altero Matteoli. The site had held the CMASA-Fiat seaplane works, where aircraft flown by Roald Amundsen to the North Pole were built in the 1920s; the old sheds were demolished in October 2007. Villa Romboli, casa Ceccherini and the Dogana Vecchia, Gabriele D'Annunzio's summer retreat, were kept for restoration.

The old customs house, Dogana Vecchia, was restored as part of the project; it had served as a summer residence for Gabriele D'Annunzio and Eleonora Duse. Villa Romboli and casa Ceccherini were also kept for restoration, while the former CMASA aircraft sheds, where seaplanes for Roald Amundsen's polar flights were built in the 1920s, were demolished in October 2007.

The marina is easy to reach by bus from nearby towns and sits close to the international airport. Visitors find it most active in the morning and early afternoon when boat work and daily operations are in full swing.

The marina lies on the left bank of the Arno's mouth, where the CMASA aircraft works once stood; in the 1920s seaplanes built there flew to the North Pole with Roald Amundsen. The old customs house, Dogana Vecchia, where Gabriele D'Annunzio and Eleonora Duse spent summers, was restored rather than demolished.
